alright im doing a yota axle swap and i took the rear end out today and  when i got to the front i got everything off except steering on the lower steering i already removed the cotter pin and took the nut off and i tried hitting it with some WD-40 and a mallet but to no avail and i dont want to brute force this thing if im not doing it right.

Whack the Pitman Arm (on the steering box)
with a 16 Oz steel hammer, not super hard,
just good solid hits, about 6 to 20 whacks and
the arm will fall off

Now you can get a propper Ball Joint press
and take it all apart if needed

The smaller Ball Joints come apart the same way
if you can get a solid hit on them
